Partial actions of groups were introduced in the 90-ies in the theory of operator algebras to endow some important classes of C^∗ -algebras with the structure of a more general crossed product. This inspired the algebraic treatment of the notion, which is being developed in several directions. After introducing basic notions I am going to give a survey on some topics related to partial actions.
